What the terms on the trends page mean, and how the numbers behind them are computed.
Sorts are Roblox's discovery shelves on the home page — the horizontal carousels labeled Popular, Top, Today's Picks, Trending, and Featured (top-tier mainline charts), plus Up & Coming, Rising, and New (rising/discovery surfaces that often feed into the top-tier shelves). Each shelf returns its games in ranked order; we pull every sort on each snapshot. When a rationale reads “rank 12 on at least one sort,” it means the game appeared at position 12 on whichever shelf gave it the best placement.
The numbered list inside each signal (01, 02, 03…) is not a unified popularity ranking. Each signal computes its own per-game score and orders the top 100 descending:
A single game can sit at #1 under one signal and #6 under another — the signals measure different things. The thresholds above are what each signal uses to rank its top 100.
Lift compares a game's peak concurrent players during a recent in-game event against its average across the week before the event started (long events are capped at their first seven days so a month-long event isn't diluted). A row reading +332% with “3,315 → 14,335” means the game averaged ~3.3k concurrents pre-event and peaked at 14.3k during it. Minimum-baseline, minimum-lift, and minimum-sample floors keep single-reading flukes and tiny games out; if a game ran several events, only its best-lifting one is shown.
CCU NOW is the latest concurrent-player sample within the past hour — distinct from the event peak, which is historical. Lift is correlation with the event window, not proof of causation: a game that went viral for unrelated reasons mid-event still qualifies.
